For instance if I have 5 PRV and I add another 5 PRV. Whenever I use my wallet it displays 5 PRV. Only a refresh will bring it to the correct value of 10. It is quite a regular small bug. 
[SOLVED] Values not constant
Hi anon8296499, this is a feature to get the most updated balance on the app. Because it is not a bug, we will consider your idea in future updates. Thank you.
Sure
